Interior Define tip
The processing fee jumps from 15% to 50% the moment upholstery — a sofa or chair — is involved instead of a stocked accent piece, so factor that steep fee into any custom sofa order before you buy, not after.
Zinus tip
If you bought your Zinus mattress through Amazon, Walmart, Costco, or another retailer instead of Zinus.com directly, this policy doesn't apply to you — that retailer's own return window and process governs your purchase instead.
